Buffer Settings for Duplication to LTO 5 Tape
We're using a Netbackup 5230 Appliance connected via 8Gb fibre to an HP MSL 8096 LTO 5 tape library with 4 drives. I've read many posts recommending leaving the buffer size as default:
If you have not modified the default buffer sizes you will need to do so - but as the one can affect the other make sure you do both
From the CLISH of the appliance follow this process:
Go to the Settings menu and then type:
NetBackup DataBuffers Number Show
NetBackup DataBuffers Size Showto see what they currently are. To change them use:
NetBackup DataBuffers Number Disk 64
NetBackup DataBuffers Number Tape 64
NetBackup DataBuffers Size Tape 262144
NetBackup DataBuffers Size Disk 1048576The disk setting is up to you but generally works well - as do the numbers used above
Hope this helps
